Expert Team on Atmospheric Composition Data Management

The Expert Team on Atmospheric Composition Data Management was formally established in 2006 by CAS-XIV, originally under the name WMO/CAS OPAG-EPAC Expert Team on World Data Centres (ET-WDC), building on a foundation of activities dating back to the 1990s. Its work is overseen by the Research Board and the Environmental Pollution and Atmospheric Chemistry Scientific Steering Committee (EPAC-SSC).
